Best bank bonuses in Connecticut

There is no online application for this account. The only way in is to book an appointment with a KeyBank banker and open it with them, so you need to be able to reach one of KeyBank's branches. The states listed are where those branches are. KeyBank's terms for this business offer set no residency rule and exclude no state, so if you can get to a branch you can open it.

New checking customers only (none in the last 12 months). Open online by December 11, 2026.

Targeted: KeyBank's terms say you must have received a personalized $500 Business Banking offer letter from them, and you open by appointment with a banker rather than online. Schedule that appointment by December 18, 2026. Make the $25 minimum opening deposit and get to $5,000 or more within 30 days, then keep a minimum daily balance of $5,000 or more for the first 90 days; if the balance dips below $5,000 even once in that window you lose the bonus. The $500 is paid within 60 days of meeting the requirements. You cannot have held a KeyBank business checking or savings account in the past 12 months, and the branch network covers AK, CO, CT, ID, IN, MA, ME, MI, NY, OH, OR, PA, UT, VT and WA. Open Basic Business Checking, which is $5 a month waived at a $1,000 average ledger balance so the $5,000 hold covers it; do not open Key Business Reward Checking, which is $25 a month and needs $7,500 to waive.

Citizens offers personal checking in 14 states plus DC: Connecticut, Delaware, Florida, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia and Washington DC. The offer terms themselves name no excluded states. You must not have been a signer on another Citizens personal checking or savings account in the previous six months, and the account has to be opened through the link on the offer page rather than in a branch.

State restricted: MA, NH, ME, RI, CT, VT. New Country Bank checking customers only.

M&T's consumer footprint covers NY, NJ, PA, CT, MD, DE, VA, WV, DC, MA, ME, NH and VT. The cash bonus is ZIP targeted, so enter your home ZIP code on the offer page to see the amount available where you live. The promo code must be entered at account opening or the bonus is forfeited, and the account has to be open by August 31, 2026 and still open when the credit is issued. The bonus is credited within 90 days of the account receiving the qualifying direct deposits. One bonus per customer, only the primary signer qualifies, and you are not eligible if you received a cash bonus on a personal M&T checking account in the last 12 months. An earlier version of the same $400 offer, promo code TG, is still open to accounts opened by July 31, 2026.

Available in CT, MA, NH, RI. New checking customers only.

New business checking customers only. Use promo code BD, which applies automatically if you open online. Online opening is available to sole proprietors only, so any other entity type has to go into a branch. Your tier is set by the average ledger balance in the third full calendar month after you open, and the money is credited by the end of the fourth month. State restricted to CT, DC, DE, MD, NJ, NY, PA, VA and WV. Open by September 30, 2026. The bonus opens Business Essential at $5 a month waived at a $1,000 average ledger balance, Plus at $15 waived at $7,500, or Premium at $25 waived at $10,000, so pick the account whose threshold your deposit already clears; the fee is also waived automatically for the first three months, which covers most of the hold. Closing within 180 days costs $50 and forfeits the bonus.

This reaches most people as a mailed offer tied to the address on the mailer, though readers report bankers honouring it in branch without the online link, so ask. Open your first new Clearly Better Business Checking or Business Advisor Checking between 4/1/2026 and 8/31/2026. Your tier is set by a single new-money deposit: $5,000 to $14,999.99 pays $300, $15,000 to $29,999.99 pays $500, $30,000 to $99,999.99 pays $750 and $100,000 or more pays $1,500. The money must not already be on deposit at Citizens. Complete 5 qualifying transactions within two months.
